PDF is a quarter-century old
1993
PDF was first
published
1994 - 2007
7 major revisions
to the Adobe
specification
2008
PDF 1.7 became
ISO 32000-1
2008 - 2018
1 major revision to
the ISO PDF
standard
2017
PDF 2.0
(ISO is the first
major update to
PDF in 10 years
32000-2) A large, diverse
ecosystem of PDF
support brings:
Unparalleled usefulness
Interoperability
Specialization
PDF dominates
SINCE
1993
IN
2016
• Trillions of PDF files
• Billions of users
• Hundreds of millions of devices
• Thousands of hardware/software combinations
• Over 2.2 billion PDF files on the web
• Over 20 billion PDF files in Dropbox
• Airbus, Boeing, and the U.S. Dept. of Justice each have over 1 billion PDFs
• 2 billion PDFs are opened every year in Outlook.com
• 73 million new PDF files are saved every day in Google Drive and Mail
• 60% of non-image attachments are PDFs in Outlook Exchange Enterprise

Context: PDF mind-share
PDF: now an open standard for a decade
PDF is a freely implementable ISO standard
There are now many commonly used PDF viewers on the market
Many users now view PDF files on (a) browsers and (b) mobile devices, both with limited subsets of full functionality
Numerous 3rd parties compete with server, desktop, and mobile PDF creation, editing, and viewing software
What PDF 2.0 is
The culmination of almost a decade of work in evolving the format to:
Bring PDF up-to-date with modern practices and use cases
Clarify ambiguities and purge application dependencies
Remove technologies not widely implemented (e.g. OPI, Flash, XFA)
Include hundreds of refinements to existing features, especially rendering,
metadata, accessibility, and reuse of PDFs
Correct errors and omissions in PDF 1.7
Incorporate improvements and feedback from decades of implementations
What PDF 2.0 is not
An entirely new file format:
PDF 2.0 retains the syntax and concepts of earlier PDF versions
A major break from the past:
PDF 2.0 was designed to behave as predictably and reliably as possible
when viewed or printed with PDF 1.x processors. Today, many PDF 1.7
programs that can open PDF 2.0, will view and print PDF 2.0 files well
enough for many users
An either/or proposition:
PDF 1.x and PDF 2.0 files will co-exist together for many years into the
future. It’s necessary to plan for both, and especially so for PDF processors
IMPORTANT NEW FEATURES
Rendering and printing enhancements
Black point compensation support - better, more predictable color conversion
Mixing hints and CxF spectral data - better, more precise ways to specify spot color characteristics and interaction characteristics
Page-level output intents allow for diverse color characteristics in PDFs combined from various sources
Improvements to transparency and halftone handling
BUSINESS CASES
Print-stream management
(enhanced efficiency)
PDF 2.0 makes a common
understanding easier
(enhanced reliability)
New rendering capabilities:
Associated files: PDF as data container
A mechanism to associate alternative representations, source files or machine-readable data with portions of PDF files
Utilization does not require PDF 2.0-aware PDF viewers; many current PDF processors already understand embedded files
BUSINESS CASES
Data payloads (e.g., for automated
invoice processing (cf. ZUGFeRD)
Source files for PDF visual
elements (e.g. application files)
Encrypted images or PDF content
items for workflows where some
PDF content needs to be secured
before printing
Encryption updates: more secure algorithms supported for better file security (AES-256, SHA-256)
New “Unencrypted Wrapper document” feature
State-of-the-art digital signature support
Long-Term Validation (LTV) signature support
Security and authentication
BUSINESS CASES
Secured document within an
unsecured “envelope” document
Electronic authentication /
revocation
Archiving / GDPR*
Regulatory requirements
*General Data Protection Regulation
The mechanism for "tagging" visual elements with their corresponding meaning has been dramatically overhauled and simplified, reducing the cost of support for these features in both PDF writers and processors
New structure tagging elements and attributes to facilitate richer, more useful document semantics
ARIA added to list of standard structure attribute owners
Many improvements to PDF 2.0’s tagging are applicable to PDF 1.7 implementations
Accessibility
BUSINESS CASES
Accessible PDF needs per WCAG*
2.0, PDF/UA, Section 508, AODA*,
etc.
Re-use of PDF content (e.g., reflow
into HTML)
*Web Content Accessibility Guidelines
*Accessibility for Ontarians with Disabilities Act
Other improvements
Associated files are based on embedded files (1998), and were already defined in PDF/A-3 (2012)
256-bit AES encryption and hash algorithms
Digital signatures for:
• Tamper and change detection
• Authentication of the document’s source (attestation)
• Revocation of an existing document or signature
Document and element metadata
• Element and content reuse via document part (DPart) metadata
WORKFLOWS
Accessibility and read aloud
Improvements to Tagged PDF and accessibility make it easier to generate PDFs optimized for:
Read-Aloud SoftwareAssistive Technology
(including screen readers) (text to speech)
“ ”
Automated content extraction
Improvements to Tagged PDF and semantic structuring facilitate automated content extraction:
More reliable indexing, text
extraction and reuse
Easier content ingestion
into machine learning and
big data processors
Semantics preservation
enhances content translation
and analysis
Enhanced proofing
More reliable rendering and printing enhances proofing:
Capable of more accurate
color representation and
conversion
More precise and dynamic
modeling of multiple ink
interactions
Combining PDF with different
output intents without color
conversion
Data delivery
Associated Files make it easier to deliver supplementary information enclosed within a human-readable PDF:
Machine-readable
content
Auxiliary content Rich content Dynamic content
Safe, secure content delivery
Advanced encryption and digital signature capabilities make it easier to:
Securely deliver private
documents with a non-
private “cover letter”
Initiate, negotiate, and
close agreements all
within a single PDF
Assure end users that the
document has not been
altered since creation
Are these really “new” workflows?
PDF 2.0 doesn’t introduce these workflows
PDF 2.0 makes these workflows easier and the results better
PDF 2.0 improves the PDF platform for electronic document output, product and application development while lowering development and support costs
NO
DEPLOYMENT
Deployment considerations
PDF 2.0 deployment timeframes are
dictated by the relevant workflow

PDF 2.0 is an evolution of PDF, not a revolution
PDF 2.0 brings greater reliability and makes
advanced PDF features easier to use
PDF 2.0 and PDF 1.x files will both be present in
the years to come
PDF 2.0 helps make customer communication
better and easier
